To, all whom .it may cancer-n.

Be it known that I, ALBERT ISKE, acitizen of the United States, residing at Lancaster, in

the countytof Lancaster'and State .of Pennsyl- Vania, have invented certain new and useful lmprovementsin Motors; and 1 do hereby def clare the-following to be a full, clear, and ex-' act description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same. This invention is an improvement on Patent No. 243, 909, granted to Anthony Isl e1 and "Albert lake on the 5th of July, 1881, in'which the tubes were extended nearly. through the 5 tained therein maybe said pipes from bulb to 'bulb under the press bulbs, inorder that the volatile liquid conforced upward through are of its vaporized particles without the escape-of the vapor itself. I

My improvement consists inthe combination of such tubes thus arranged, butbent at their ends within said bulbs,a'nd the necessary heating, supporting, and power-transmitting devices, the bending ofthe tube ends serving to prevent the liquid from running back down the tubes.

In the accompanying drawings, Figure 1 represents-a front elevation, the end of the easing being broken away of a motor embodying my invention; and Fig. Zrepresents'a similar view taken at rightangles to Fig. 1.

A designates the base of the motor; B, a lamp thereon; O, a casing inclosing said lamp and extending ab'oveit; D, a curved deflectorplate above said lamp; E, two standards raised from the sides of said casing; F, ashaft having 1 its hearings in the tops of said standard; G,

a series of tubes arranged like the spokes of a wheel, but attached 'at' their middles to said shaft; and of said tubes. 7 p 1 The sides of casin'gA; are arched over to form an upper deflecting-plate, I, which is provided with a slot,i, to allow the passage of the tubes G while said tubes and bulbs are turning with the shaft. For the same purpose with regard to said bulbs the ends of the space between the deflector-platesD and I are left open. The bulbs in passing through said space are heated by the lamp B and the hot air therefrom,which H, the bulbs arranged on the ends Serial No. 271.319. (No modelJ pair, and the ends of the tubes extending through the centers of the bulbs-and nearly across the hollow interiors thereof, the expansion of a part of the liquid in each bulb successively as it comes under the influence of the heat, as aforesaid, will force the remainder of said liquid up througlithe tube to the other bulb of the pair, and the weight of the liquid in the latter bulb will then cause it to descend, turning the shaft. Each pair of bulbs acting in rapid succession will cause the rotation also to becomerapid. The shaft F carries a flying with a pinion, L, for transmitting motion. An annular shield, N, attached to the tubes G, prevents'the heat from affecting the-upper bulbs... t:- v

Heretofore I have in some instances,asshown in my patent, No. 2t2,454, bent the ends of the tubes in the direction of rotation at and near the points where they ase attached to the The defect of this 'construction is that'the bent end of the tube attached to each bulb is during the lower part of its travel at first above the until the gradual elevation of said bulb, as re,- tation proceeds, .places. the bent part of the tube at the bottom. Until this last position is taken only a part of the liquid at most can be-forced up through the tube by the expanas the vapor will be free to escape through the tube to the upper bulb without forcing the liquid up 'before it. In consequence the'sup ply of liquid to the upper bulb will be lessened and its weight will in part be offset by the liquid which remains temporarily, as, stated, in the lower bulb. As the entire power of this of the upper bulbs, supplied with liquid,over the lower bulbs, deprived thereof, these considerations are of great importance. I have also sometimes employed, as shown in mypatout, No. 243, 909, a series of straight tubes extending nearly through the bulbs, so that their ends would be below the mass of the liquid in the latter during the lower part of the revolubulbs, the said tubes not entering the bulbs.

sion of the vapor, and at first not even that,

motor is derived from the excess of the weight 4 having been previously supplied with volatile v liquid nearly suificient to fill one bulb in each Wheel, J, and a gear-wheel, K, the latter meshentire mass of liquid in said bulb and afterward abo ve the greater portion of said l1qu1d,-

tion of said bulbs. In this way the defects incident to the construction above referred to are avoided; but if the liquid in each pair of bulbs and tube is sufiicient to three-fourths fill one of the bulbs it will of necessity cover the upper end of the tube during the latter part of the first fourth of its rotation, starting from the highest point which said bulb attains in its rotation. While the end of the tube is thus immersed, a part of the liquid will run back into the lower bulb unless held by the centrifugal force due to rapid motion; but such centrifugal force is hardly appreciable when the bulbs are revolving slowly, as in starting the motor, or when its speed is temporarily slaekened for any purpose, and even when the a rotation is rapid the centrifugal force of a motor of small diameter cannot be relied on to hold any considerable weight of liquid in place in the upper bulbs. Whatever liquid runs down to the lower bulbs of course acts doubly against the efliciency of the machinefirst, by lessening the gravity of the operative side thereof, and, secondly, byjncreasing the counter-balance on the other side. These'disadvantages will not occur if only a small amount of liquid is used, as it will not then cover the upper end of the tube, nor run down through the same; but the motor will be correspondingly weak. It is important to use the greatest practicable amount of liquid, and at the same time to insure getting-the full benefit of the weight thereof in rotating the motor and its shaft. This purpose is effected by the bent ends of the tubes, which are extended in my present improvement nearly through thebulbs, as in Patent No. 243,909, and then turned backward in the direction opposed to that of rotation. Suflicient liquid may be used to more than three-fourths fill the bulb, and the upper end of the tube will nevertheless be always above the surface thereof until the tube is horizontal, and the lower end will be immersed in the liquid so long as there is any liquid in the bulb.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1 A motor provided with bulbs for holding vaporizable liquid and tubes connecting said bulbs, as stated, the tubes being extended nearly through the bulbs and bent within them in a direction opposed to that of rotation, for the purpose set forth.

2. In a motor, the combination of a series of bulbs, their connecting-tubes, the shaft on which they are mounted,and a calorific device below them, with a plate or shield which protects thebottoms of the bulbs from the direct heat of the flames and causes the same to pass around-and over the bulbs, this'shield or plate being slotted to allow the passage of the tubes as they turn with the shaft, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
